Hold L, then open a booster pack and it should have a rare shiny word card.

REMEMBER: You must have unlocked Mai and get Zombrya The Dark pack. Duel anyone while holding L most of the duel. Continue holding L and choose Zombrya The Dark pack. You are not certain to get a Spirit message or Destiny Board, but it is very likely.
